There are multiple project files located in the zip. After you extract
them. you must navigate to the "\XS Pet Robot\XS Robot" folder.

Modifying the Code

I strongly suggest you make this Troubot Robot as a training exercise before you start to
hack and slash at the scripts. There are some rules and sequences that are
important in this project. You must have all the pieces completed and then
assemble them, in order. Instructions to make changes are found in Part
7 - Modifying your Troubot Robot.
